VALVE T all whom it may concern";

Be it known that I, HERMAN F. RosEN- ORANS, citizen of the' United States, residin at Durand, in the county of Shiawassee an State of Michigan, have invented certain new and usefullmprovements in Valves, of which the following is a specification.

My invention relates to new and useful improvements in valves and operating mechanism therefor and more particularly to valves of the balance type for use in high pressure water supply mains and part1cularly in connection with a water supply system such as that coveredby my copendmg application filed August 16, 1912, and bear ing the Serial No. 715,522.

Ehe primary object of my invention 1s to provide a cutoff valve for high pressure water mains which will be practically balanced in its action,'requiring but little force to either open or close the valve.

A further object of my invention is to provide a valve in which the movable part need be moved only through a slight distance to fully open the valve. And a still further object of my invention is to provide a valve of the above described type in which the movable part comprises a hollow cylindrical valve mounted for reciprocation in the valve casing and la a simple linkage for reciprocating said valve, thereby providing a ready means for mechanically openingand closing the valve so thatthe passage of wate. hrough the same may be automatically governed.

With these and other objects in view, my invention willbe more fully described, illustrated in the accompanying drawing, and then specifically pointed out in the claims which are attached to and form apart of this application.

In the drawing: Figure 1 is a central longitud-inal section taken through the valve casing and valve, showing the valve operating linkage in elevation; Fig. 2 is atop plan view of the valve proper, showing the valve stem in section; Fig. 3 is a central longitudinal sectional view, showing an elbow valve and casing constructed in accordance with my invention; Fig. 4 is a section on the v on of Letters Patent.

line 4' 1 of Fig. 3, looking in the direction of the arrows; Fig. 5 is a central longitudinal sectional view of a further 'modified form of my valve, showing the same employed as a straightaway valve; Fig. 6 is an end elevation of the valve shown in Fig. 5, 1showingthe operating mechanism of the va ve.

Corresponding and like parts are referred divided transversely adjacent its central portion by a web 13,- and end portions 14 and 15 adapted for connection with the pipes of the water main and having inlet and outlet passages 16 and 17, respectively, the former of which communicates with that portion of the central valve chamber 12 above the web 1.3, while the latter leads from that portion of said chamber below the web.

The central valve chamber 12 extends by of the valve casing and the-top of the valve casing surrounding said chamber is provided with 'a threaded flange 18 adapted to receive a bonnet 19 closing the 11 per end of the valve casing, a suitable pac (ing ring 20 being preferably interposed between the valve casing andbonnet. The bottom of the valve casing is provided with a downwardly directed flange 21, the edge of which is plane surfaced and the open lower end of the chamber 12 is closed by a valve seat 22 hav- -ing a peripheral flange 23 for engagement against the flange 21, a packing ring 24 being preferably interposed between said flanges, the valve seat being secured in place by a plurality of bolts or other suitable fastenings 25 passed through the flange 23 of the valve seat and into the flange 21 of the valve casing.

As shown, the central valve chamber 12,

4,5 1 end of the valve stem still seats in the upper I immediately above. and below the web 13,

is enlarged to permit the .free passage of water through the valve. The valve seat proper is formed by a semi-spherical extension 26 integrally connected with the body portion 22 by a reduced neck 27, said valve seat proper being so formed as to extend upwardly within the enlarged lower end of the central chamber of the valve casing with its lane surface uppermost and disposed in a "horizontal plane. It'will therefore be seen that when thevalve proper is raised from engagement with theupper face of the valve seat. 26, water passing through the valve cannot only flow directly to. the outlet passage 17, but can also flow to said passage indirectly through the annular space orcham- I ber 28 between the body portions 22 and 26 of the valve seat:

The-valve whichI employ in this valve casing consists of a hollow cylindrical valve 29 fitting in the central portion of the valve chamber t2 and engagingby its outer face against the side walls of the web 13 in such amanner that when seated by its lower edge upon the upper face of. the valve'seat, all passage of water from the upper portion of thevalve' chamber 12 to the lower portion thereof is cut off. This cylindrical valve is provided at its upper and lower ends with spiders 30-by means of which it is mounted upona 'valve stem "il -thelower end fof' which seats in a socket 32 formed centrally in the 1 valve seat and the u per end of-whichextends through a stu v g box in the bonnet 1 and beyondtheendof the bonnet. The

valve seat islpreferably provided. in its valve receiving face with an annular groove -in which is seatrLa-paQking ring'33 upon which the valve bears when in closed posithin ,and the socket .32 isso proportioned that when the valve is in closed position, the lower-end of the valve stem extends nearlyfto. the bottom of the socket while, when the valve is in open position, the lower portion of the socket.

The upper edge of the valve 29 is preferably--beveledinternally as shown at 34 to oitfer-lessres1stance to the passage of the 1 Water through the valve'and also to decrease the effective areaofie red by the valve to water .pressure and tending to prevent the opening of, the valve.- As will be readily seen, this valve is practically of the balance type and but little force is required to' open the valve or'to hold the valve when in open position. I

The upper end of the valve stem which I projectsbeyond the bonnet, is prov ded with a laterally directed,'.lo 1gitudinally bored head 35-and pivotally connected to this hea l, by a bolt 361% a link 37, the free end of which is pivotally connected by a second bolt 38 to the intermediate portion of a lever 39 which in turn is pivoted upon a bolt 40 passed through spaced cars 41, preferably formed integrally with the bonnet and upstanding therefrom. The bonnet is also provided, in radial alinement with these cars, with an outward y and. upwardly curved arm or lug 42 which forms a stop for limit-. ing the swmging movement of the lever 39,

any suitable source of power of some means ofrocking the lever 39.

In Fig. 3 of the drawings, '1 nave illustrated asomewhat modified form of valve construction in which the valve casing, des-' ignated asa whole by the numeral 43, is substantially spherical in shape and provided with 'a diametrically extending valve chamber 44 opening through the valve casing'at both ends and providing an outlet passage 45, the casing at 'the mouth of this passage being flangedjas shown at 46. The valve .casing is further provided} with an inlet passage 47 extending substantially at right angles to the valve chamber 44 and communicating with the upper portion thereof and the casing at themouth of this passage is threaded to receive the inlet pi e 48.

The valve chamber 44 is. divided as in the previous form bya transverse web 49 provided with a centrally formed valve passage forthe valve 50. This valye is identical in construction with the valve 29, previously described, and is mounted upon lt lfie valve stem 51 in the same manner. valve stem however, terminates either above or flush with the lower end of the valve.

The upperr end of. this, valve stem pa$es through the bonnet 52 andstufling 'box 53 and is- 'pivotally connected as shown at 54 to a slotted lever arm 55 which in turn 1s pivoted as at 56 between the spaced ears 57 carried by the bonnet, The valve seat in f this form of valve CODStIHCtlOIPCOIlSlStS of a circular plate of metal 58 secured upon a plurality of spaced studs 59, the free ends of which are secured to the inwardly directed ears 60 of an annular ring 61, the g body portion of which is clamped between the fian'ge46 of the valve casing and a correspopdinmflange 62 formed upon the free end of the, outlet pipe 63. By this means, the valve seat 58 is maintained in'spaced relation below the web 49 and above the discharge endof the-valve casing andsin a proper ima es I nection with a straightaway valve. In this,

form, the valve casing 65 is substantially cylindrical inshape being bulged somewhatas shown at 66 to provide an enlarged portion 67 of the longitudinally extending passage 68. This passage is slightly reduced intermediate its length as shown at 69 to form a bearing for the valve proper 70, this valve being identical in construction with the valves 29 and above described. The valve seat 71 is also identical. in construction with the valve seat 58 of the valve shown in Fig.

3 and is secured in like manner by studs or pins 72 which in this case are threadedby one end into the valve seat and by their opposite ends into the ears 7 3 of the ring 74. This ring is seated between the annular flange 7 5 of the valve casing and the corresponding flange 76 of the outlet pipe 77 and the valve seat is therefore properly maintained in position. The inlet end of the valve casing'is thickened and plane faced as shown at 78 to provide a seat for the flanged end 79 of the inlet pipe '80, the flanges 7'9 and 78 being secured together by bolts or other suitable fastening devices. i

As will be. apparent, the valvestem 81 of this valve extends longitudinally and centrally of the valve casing and in alinement with the axes 'ofthe inlet and outlet pipes. The free end of the valve stem is pivotally connected .to a link 82 and the free end of this link is in turn connected to a crank arm 83 carried by a shaft 84. This shaft 84:, as best shown in Fig. 6 of the drawings, extends through the valve casing being mount- Y ed for rotation in suitable bearings 85 formed upon the valve casing and is extended at one end to receive an operating lever 86 by means of which the valve may be opened and closed.

It will be apparent that the valves shown in Figs. 3 to 6 inclusive are merely somewhat altered embodiments ofthe principles illustrated in the valve construction of Fig.1, the valve in all cases being identical and operating in the same manner.

It will of course'be understood that the valve stem in the form shown in Figs. 1 and 3 may, if desired, be threaded to engage with threads formed in the bonnet and the valve therefor operated by cans of a hand wheel. In fact I do not ish in any way to limit myself to the specific structure illustrated and described as various minor changes in details of construction may be made at an time without departing from the spirit 0 my invention;

As shown, the upper end of the valve is flared to provide a beveled inner face and an outwardly inclined outer face which seats upon the beveled upper face 29 of the web.

By beveling the upper face of the valve in- 1 teriorly in'this manner, the direct pressure of the water upon the valve is reduced and at the same time a firmer andcloser seating .of the valve against the web is obtained.

Having thus described the invention, what is claimed as new is:

1. valve including a valve casing having a valve chamber divided by a transversely extending web provided with a valve passage, one end of said valve chamber extending through the casing to form an outlet passage, a ring securedto the outer face of the casing about said outlet passage and provided with inwardly directed ears,

studs secured to the ears and extending inwardly of the valve chamber, a valve seat carried by said studs, and a hollow cylindrical valve movable in the valve passage and adapted for engagement with the seat.

2. A valv'e including a substantially cylindrical valve casing reduced intermediate its length toform a valve passage and enlarged adjacent the passage to form a chamber having a' discharge passage leading through the valve casing, a seat supported centrally of said chamber, a hollow cylindrical valve movable in the valve passage and adapted to engage by one end against the valve seat, and means for reciprocating said valve, said means including a valve stem carried by the valve, a shaft journaled through the valve casing and carrying a crank arm, and a link pivotally connecting the crank arm and free end of the valve stem.

3. A valve including a valve casing having a valve chamber divided by a transversely extending web provided with a valve passage, one end of said valve chamber extending through the casing to form an outing inlet and outlet passages enlarged into chambers at their inner ends, a web dividing the casing between the chambers and provided with a central passage, a valve seat supported in spaced relation to the web and substantially centrally of the outlet cham- & 1,143,999.

.ber, the space between the web and seat Eeing entirely unobstructed, as well as the pace surrounding the seat, and a hollow eylindrical valve open at it's ends reciprocally 5 mounted in the passage of the web and movable in'to arid out of engagement with the seat.

In testimony whereof I aflix my signature in presence of two witnesses.
